A Non-Cross-Coupling-Based Approach to Arene-Bridged Macrocycles and Their Use in the Development of Annulative Pi-Extension Methods
(2018-07-31)
The synthesis of strained macrocyclic benzene-containing molecules has been an area of interest for decades. However, the synthesis of macrocyclic structures that contain adjacent benzene units linked at their 1 and 4 ...
Contact-free Breathing Rate Monitoring with Smartphones: A Sonar Phase Approach
(2018-07-30)
Vital sign (e.g., respiration rate) monitoring has become increasingly more important because it offers useful clues of medical conditions such as sleep disorders. There is a compelling need for technologies that enable ...
Guidelines and Application for Designing Visually Compelling Products
(2018-07-30)
Today, with the development of modern civilization, the pursuit of product appearance has never ceased. However, to design a visually compelling product for the majority is a challenge for designers or companies. By studying ...
Perceived Factors that Influence the Success of Vertical Transfer Students in Agricultural Education: A Delphi Study
(2018-07-30)
Community college students face a unique set of challenges when making a vertical transfer to a four-year university. This study utilized a Modified Delphi technique to identify the perceived factors that influence bachelor’s ...
Towards the formulation of a new multi–determinant electron propagator for open–shell molecular systems
(2018-07-30)
The efforts of this thesis are focused on extending the capabilities of the current single determinant electron propagator formalism to a formulation in which multiple determinants can be employed, enabling the formulation ...
Torsional Resistance of Drilled Shaft Foundations
(2018-07-30)
Drilled shaft foundations are commonly selected by public transportation agencies to support mast-arm traffic sign and signal pole structures. Those inverted L-shaped structures are subjected to lateral and torsional loading ...
Body shape evolution of African/Asian minnows of the genus Labeo Cuvier 1817 (Cyprinidae, Labeonini) and variations in Labeo parvus
(2018-07-30)
Morphological variation or similarities among organisms are not only a result of common evolutionary history but can also emerge because of convergent adaptations to similar habitats. Therefore, an organism’s morphology ...
Ex vivo comparison of the bursting strength of surgeon’s knot compared to self-locking knots for closure of ventral midline celiotomy in horses.
(2018-07-27)
It is not uncommon for the equine population to experience abdominal pain referred to as
‘colic’. It is estimated that approximately 9% of the general population of horses that experience
colic require surgical intervention. ...
Synthesis of Janus Nanoparticles using a Packed Column and their Applications
(2018-07-27)
